This requires the RTC clocks, etc, to be enabled prior to use and |

not all boards with this IP block on it will have the RTC in use. |

config BOOTCOUNT_ENV |

bool "Boot counter in environment" |
|
help |
|
If no softreset save registers are found on the hardware |
|
"bootcount" is stored in the environment. To prevent a |
|
saveenv on all reboots, the environment variable |
|
"upgrade_available" is used. If "upgrade_available" is |
|
0, "bootcount" is always 0, if "upgrade_available" is |
|
1 "bootcount" is incremented in the environment. |
|
So the Userspace Application must set the "upgrade_available" |
|
and "bootcount" variable to 0, if a boot was successfully. |
